Meckel's diverticulum represents one of the most common congenital anomalies of the gastrointestinal system. It appears in 1-3% of the general population. In this case study we presented 72-year-old male patient who was admitted in the Center for Abdominal Surgery, Clinical Center of Montenegro. The symptoms were diffuse, severe abdominal pain, nausea and vomiting with intestinal obstruction. After the preoperative diagnostic procedures we performed resection of the terminal ileum and T-T anastomosis. Whenever the patient has the clinical findings of acute abdomen and no matter if patient is in elderly, we should think on complications of the Meckel's diverticulum.
